Modelling of losses in multi-stage axial compressors with subsonic conditions
(North-West University, 2003)
The need was identified to develop an analytical performance prediction code for subsonic multistage
axial compressors that can be included in network analysis software. It was found that
performance calculations based ...
A new integrated procedure for energy audits and analyses of buildings
(North-West University, 2003)
A rapid growth in the national electricity demand is placing an ever-increasing demand on the national electricity supply utility, Eskom. Projections show that the load demand in South Africa may exceed the installed ...
Steel slab surface quality prediction using neural networks
(North-West University, 2003)
Columbus Stainless grinds the majority of the steel slabs that are produced to improve the surface quality. However, the surface quality of some slabs is good enough not to be ground. If a reliable method can be found to ...
The design and implementation of information systems for ESCO energy savings software
(North-West University, 2003)
Electricity cost of buildings is a major expense for building owners. Improvements in the efficient utilisation of energy is therefore of concern to this economic sector. Unfortunately, existing energy audit tools are ...
Simulation and optimisation of gas storage tanks filled with capacitance
(North-West University, 2003)
The Pebble Bed Modular Reactor (PBMR) is a revolutionary small, compact and safe nuclear
power plant. It operates on a direct closed Brayton cycle. One of the unique features of this
concept is its load following capability ...
The numerical modelling of a flue gas precipitator
(North-West University, 2003)
Suspended fly-ash particles in industrial emission gasses have a major degrading effect on the whole environment. Electrostatic precipitation is one of the oldest and most effective gas-cleaning processes used today. ...
Network modelling of transient heat exchanger performance
(North-West University, 2005)
This study investigates the applicability of the thermal-fluid network approach to the modelling of transient
heat exchanger performance.
Two different solution algorithms, namely the Implicit Pressure Correction Method ...
Delay modelling and synchronisation of telecontrol networks
(North-West University, 2004)
Eskom, South A6ica's largest supplier of electricity, uses a vast telecommunication
network to control and monitor all operations in remote locations such as substations. As Eskom expanded the electricity network across ...
Numerical simulation of systems of rigid bodies
(North-West University, 2004)
This study investigated the various techniques available for rigid body system simulation, thus
providing a thorough overview of the latest relevant literature. N became apparent that no
engineering level accurate impulsive ...
Designing a dynamic thermal and energy system simulation scheme for cross industry applications
(North-West University, 2004)
The South African economy, which is largely based on heavy industry such as minerals
extraction and processing, is by nature very energy intensive. Based on the abundance of coal
resources, electricity in South Africa ...
